is one of the world’s dangerous disease and it can be transmitted easily through sexual
intercourse. Consuming ART (Antiretroviral) medicine right before HIV-infected patients
want to do their sexual activities is one of the solution to prevent the HIV-transmission.
However, there are difficulties to apply ART to HIV-infected patients regularly. One of those
difficulties is the patients always forget to consume their ART medicine right before they
want to do their sexual event. Hence, this research aimed to determine HIV-infected patients’
sexual activities by predicting their travel behavior, APP usages and the preparation point of
their sexual activities based on their smartphones’ sensor data. This smartphone’s sensor data
includes mean and standard deviation of their smartphone sensors (including accelerometer,
gyroscope, and orientation sensor), distance, and speed data. Those smartphone sensors’ data
were collected using self-developed APPs for smartphones under Android System. For
predicting HIV-infected patients’ travel behavior and APP usages, this research used one of
machine learning algorithm, that algorithm was Random Forest. Meanwhile, for determining
the preparation point of HIV-infected patients’ sexual activities, this research built selfdeveloped algorithms, which divided into two types: algorithm for determining HIV-infected
patients’ sexual activities outside their house and algorithm for determining HIV-infected
patients’ sexual activities inside their house. The result for predicting HIV-infected patients’
travel behavior showed that the highest accuracy was obtained by using accelerometer sensor
only with 92.20% accuracy and the activity with the highest accuracy was Riding Scooter.
The result for predicting HIV-infected patients’ APP usages showed that the highest accuracy
was obtained from using orientation sensor data only and using APP categorization based on
their data type with 76.01% accuracy. Meanwhile, most of the APP categories were confused
with Social Media APP because their data type was similar with Social Media APP’s data
type. The last one, for determining HIV-infected patients’ sexual activity, this research could
determine 6 out of 8 sexual activities outside their house which already determined by theiv
researcher before based on GPS location. However, the algorithm for predicting sexual
activities inside patient’s house could determine 22 possible sexual activities which already
defined by the researcher before according to sensor data analysis.
